tap-spec is a Node.js library that formats TAP (Test Anything Protocol) output to resemble Mocha's spec reporter, making test results more readable and visually appealing. It's designed for developers working with TAP-compliant testing frameworks like Tape who want cleaner, more intuitive test output in their terminal. The tool can be used both as a streaming library or via CLI, and is particularly useful for JavaScript developers running tests through npm scripts or continuous integration pipelines.
